About this gig

Is your business still running on .NET Framework 4.x, ASP.NET MVC 5 or WebForms? I help you move to modern .NET with a planned, step-by-step migration instead of a risky rewrite.


What I offer:

  • Migration assessment: dependencies, blockers and an effort estimate
  • Upgrading class libraries and services to .NET 8
  • Porting ASP.NET MVC / Web API to ASP.NET Core
  • Replacing unsupported packages and APIs
  • Moving configuration, DI and logging to modern patterns
  • Updating Entity Framework 6 to EF Core, where it makes sense

How I work:

  1. Review your solution and agree on a migration plan
  2. Migrate in small, testable steps
  3. Verify that behavior matches the original app
  4. Hand over code and notes on what changed

What I need:

  • Source code access and a way to run the current app
  • Any existing tests and a list of the critical workflows

WebForms and WinForms can't be ported directly. I'll explain your options (rebuild, keep, or wrap) in the assessment.


Every legacy codebase is different, so please message me before ordering. The Basic package is a paid assessment that tells you the real scope.
